A kind of active ventilation screen window isolating PM2.5
Technical field
The present invention relates to a kind of ventilation screen window, particularly relate to a kind of active ventilation screen window isolating PM2.5.
Background technology
The window frame of house window screening known to us is made up of rustless steel gauze at present, is arranged on the inner side of house glass window, when we open the window, along with the energy of flow of outside air plays certain ventilation and prevents the effect of some mosquitoes.But due to the area bigger for the dust such as north, owing to this kind of window screening emptying aperture is bigger, it is impossible to prevent the dust in air, but if window screening Tai Mitai is tight, can affect again ventilated.
Application No. 200720115858.8 Chinese patent proposes a kind of high density dust-proof window screen, multiple tracks cross arrangement anyhow form framework and which is provided with a floor height density gauze, and framework combines as a whole with gauze.Its compact conformation, lightweight, for more traditional rustless steel window screening, can guarantee that ventilated in the case of, moreover it is possible to effectively prevent outside air dust and micro-worm.
Application No. 200520106751.8 Chinese patent is then to propose a Novel window screen utilizing electrostatic absorption principle.Non-woven fabrics with electrostatic is compressed in non-conductive gauze substrate, forms drainage screen, utilize electrostatic adsorption to carry out purification filtering to entering indoor air.Can effectively reduce dust pollution in Urban House.
Application No. 200820003417.3 Chinese patent is to propose one to add small fan active ventilation type screen window.I.e. two parts up and down at its master window frame respectively install many small-sized fanses, then cover air insulated plate between upper and lower fan, install high-density air drainage screen by outdoor side.Rely on fan effect actively to carry out indoor and outdoor ventilation, and rely on high density filter net to carry out anti-dust.Although but first two window screening can prevent the dust in micro-worm and outside air well, can not carry out indoor and outdoor ventilation initiatively for the first, the second window screening is then the effect that can not play ventilation completely, but also affects daylighting.And the third active ventilation screen window meets dust-proof, and can take a breath on one's own initiative.But structure is complex, whole screen window thickness is relatively big, and I thinks that high density filter net has more part to be to waste.
Summary of the invention
In order to overcome the complex problem with waste of material of active air hole knot structure, on the basis of ensureing well to take a breath in indoor, improve stock utilization, improve daylighting, simplify screen window overall structure.
The present invention proposes the active ventilation screen window of an isolation PM2.5 improved.Technical scheme is as follows: first at respectively one fixed support that can place several (depending on screen window size) small fans of addition of master window frame, then can be spaced one fixed width in these supports and one thickness one centimetre, the small fan of long a width of 10 centimetres * 10 centimetres are installed, it is similar to computer CPU radiator fan, small fan respectively embeds a piece of high-density air drainage screen by outdoor side or high density filter is cotton (depending on air ambient) up and down, and its width is identical with the height of small fan.One piece of indoor-outdoor air insulating glass is put into up and down between fan.The effect that thus can lean on small fan blows to indoor the air after filtration, plays the effect to indoor air-changing.
The invention have the advantage that the structure simplifying screen window, the use after be more convenient for engineering construction and user.Decreasing high-density air drainage screen or the consumption of the many filter pulps of high-density air, which raises the utilization rate of material, daylighting is more preferable.Dust and the micro-worm that can also effectively prevent outdoor while indoor being carried out good ventilation ventilation enter indoor.

Detailed description of the invention
Below in conjunction with specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention, after having read the present invention, those skilled in the art all fall within the application claims to the amendment of the various equivalent form of values of the present invention and are limited.
Embodiment 1
First small fan is installed on the fan Fixture that master window frame is upper and lower.Then at upper and lower small fan by outdoor side, high-density air drainage screen is inserted respectively in master window frame and support bracket fastened slot.Between fan Fixture, one block of air insulated glass is installed up and down.Screen window main body installs.
Above are only the detailed description of the invention of the present invention, but the design concept of the present invention is not limited thereto, all changes utilizing this design that the present invention carries out unsubstantiality, the behavior invading the scope of protection of the invention all should be belonged to.In every case it is the content without departing from technical solution of the present invention, any type of simple modification, equivalent variations and remodeling above example made according to the technical spirit of the present invention, still fall within the protection domain of technical solution of the present invention.
